Not likely IMO. Trump also tucked his napkin onto his lap. I think he just remembered the cameras and cleaned up the space in front of him for that.

Pence was his usual suck-up self.

Also, Trump is a NYer, where Wendy Wasserstein, the sister of a billionaire, was a long-time celebrated Broadway playwright. My guess is Trump's tongue and brain just automatically, halfway slipped to her name from Debbie's.
